UBIFS With Linux 4.10 Implements Fscrypt-Based File Encryption
The main feature addition to UBIFS with Linux 4.10 is native file encryption support.
UBIFS, the Unsorted Block Image File System for raw flash memory media, has file encryption via fscrypt with Linux 4.10. This fscrypt file-system encryption support is what powers EXT4's file encryption and F2FS per-file encryption while now UBIFS has wired it up for offering optional file encryption.
The UBIFS file encryption took just about one thousand lines of code thanks to the fscrypt framework and encrypts file contents as well as the file name.
Other updates in UBIFS include some fixes, honoring the dirty_writeback_interval sysctl, and removal of dead code. More details on the UBIFS changes for Linux 4.10 via this pull request.
